Thanks for the really detailed update, good to see search always 
improving with Lucene. I am eagerly awaiting the av11n support, and I 
know only you can pull this off, having said that - if you need any help 
with it, just let me know.

I just filed two BD bugs:

I can take a look at fixing these myself (unless they are already fixed 
/ being worked on?), they now affect FireBible users too, since I've 
integrated the book installer from BD. Please let me know if you have 
any thoughts on either (esp where you prefer the button on 144). I had 
raised these on the mailing list earlier but received no response, I 
guess the JIRA is the most appropriate place for them anyway.

Manfred, I couldn't locate the start of your thread, but I assume you 
switching MacSword over to using JSword? Glad to have you over!

In Him,
